To (ZZZ cvhom'it may mm: I

Be it 'known' that I, GEORGE LUX, citizen of the UnitedStates, residing at Quakertown, in the county of Bucks and State of Pennsylvania, have invented certain new and useful Improvements in Shuttle Spindies and Cop Tube Holders Therefor, of which the following isa specification.

This invention relates to textile weaving apparatus, and has particular reference to an improved form of shuttle spindle and cop tube holder therefor.

The primary object of the invention is j to provide a shuttle spindle and a cop tube holder having cooperative means for positively holding cop tubes upon such spindle. Another object is to provide a device constructed to receive and eifectively hold a cop tube, andto provide a special form of shuttle spindle for reception of said cop tube holder, the :cop tube holder and spindle being provided with cooperative-means for efiectively retaining the cop tube holder upon said spindle. '25

Stillanother object ofthe invention is to provide a'shuttle spindle and cop tube holder therefor, which embrace the desired qualities of simplicity and durability of coni struction, as well as eificiency in operation, "30

in preventing slipping of the, cop tube from the spindle. 1

'Still another object of the-invention is to provide for the eifective mounting of cop tubes upon.shuttle. spindles with facility and ease and Without requiring twisting or other distortion of the, cop tube, such as would result in loosening the-silk or cottorigwound uponlthe tube. as well as wast-. ingof' such silk or cotton, and whereby the cop tube willbe preservedffor re-use.

Other objects will appear as the nature ofthe invention is better understood, and the same consists infthe novel form, combin'ation, and'arrangement of parts hereinafter more fully described, shown in the accompanying drawin'g, and claimed;

Inthe drawings, wherein like reference characters indicate corresponding parts throughout the several views V '50 igure 1 'is' a side elevational :view showing a shuttle spindle and a cop tube holder therefor constructedin accordance w th the present invention, the cop tube holder be ingj loc kedto the spindle.

igure 2 is a'bottorn'plan view of the device shown in Figure 1, with the cop tube illustrated in position by dotted lines.

Figure 3 is a view similar to Figure 1, of the shuttle spindle with the cop tube holder removed, and

Figure 4 is a transverse sectional view taken substantially upon the line 44L of Figure 1.

Referring more in detail to the drawings, 5 indicates the shuttle spindle, which is pointed at its outer end as at 6, and which is enlarged in the usual manner as at 7, to provide a head formed with a transverse opening 8 by means of which the spindle is pivotally mounted in the shuttle, the head 7 being flat as at 9,0n its upper side, for cooperation with the usual spring, not shown, by means of which the spindle is only swung into proper position longitudinally within the shuttle. The construction thus far described is usual and well known in the art and forms nopart of the present invention, except in combination with construction to be now described. 1 l

As shown clearly in Figure 3, the inner end portion of the spindle 5 is tapered as indicated at 10 so as to gradually increase in diameter. toward the head 7, and projecting outwardly and latcrally frorn the head 7 and overhanging the inner end of the tapered portion 10 of the; spindle 5 is a rigid hook member 11, whose free end is directed toward the spindle as indicated at 12.

The cop tube holder consists of a tapered sleeve 13, that is tapered both externally and internally, whereby said sleeve may. be fitted onto the tapered portion 10 of the spindle 5, snugly but rotatably, for a purpose which will presently become apparent. The outer end of the sleeve 13 is provided with a plurality of longitudinal slots as at 14 so as to divide the outer end of said sleeve into a pluralityof j aws'15that are resilient and nor-, mally contracted to permit the larger end of the usual cop tubeindicat'edby dotted lines at 16, in Figure 2, to be fitted thereon. The jaws 15 are normally contracted so that when the sleeve 13-of the cop tubeholder is forced toward the head 7 of the spindle 5 beyond a predetermined oint, the jaws 15 will be slightly expanded: so as to tightly grip the interior of the, larger end of the cop tubej16,whereby accidental slipping of said cop tube 01f of theholde'r sleeve 13 is pre vented.

40 i tortion'of'cop tubes, and that the'latter may which thefinwardly directed free'end por-- The present invention embodies the provision of means for causing this long tudinal movement of the sleeve 13-" toward theheadi 7, for securing the cop tube upon'said sleeve 13, and this means preferably constitutes means for also positively 'l0oki11g the' .sleeve.

13 on the tapered portion 10 of the spindle.

In the form of the invention shown, this means comprises an annular flange 17 that is rigid with the inner end of-the 'sleeve' 13,"

and that is provided with a cam face along tion of the hook member'll is adaptedto ride when the spindle. 5 and sleeve13 are relatively rotated for causing movement of the sleeve .13 toward the head 7 as mentioned above. vIn order to permit engagement of the sleeve 17 behind the hooked end '12 of the hook 11, vsaid flange 17 is provided with a peripheral notch, as at 18, adapted to be aligned with the end 12 of the hook 11, when the cop tubeholder is slippedontothe spindle. The notch 18 is slightly wider than the hook. 1l, so that the flange 12 may pass thefree end of said hook, after which the relative rotation referred to above results in engagement of thehook behind the flange 17 for positively locking the cop tube holder upon the spindle, and for urging it.

toward the spindle head, so as to expand the j aws'15 into tight gripping engagement with theinterior of the cop tube 16. By simply reversing this operation, the copitube holder may be readily removed, whereupon the jaws 35 15 will automatically contract so ithatfthe top tube may becremoved therefrom and a new cop'tube substituted upon whichan additional supply of thread is wound. I V is' thus apparent that the use of the presentfdevice requires no damage-ordis- 7 be made without departing from the spirit and scope of the invention as claimed. lNhat I claim as newvis: 1 1;.
